C++ type cast issue

[arkjedrz]

If provided JSON contains numbers - the are improperly stored as boolean.
Changing the order of execution in any_to_kvsvalue seem to affect results. E.g., normally double values are stored as booleans, but modifying code to handle double before bool type cause bool tests to fail.
I was not able to reproduce the issue using only any_to_kvsvalue.

Reproducer is available in #28.

Hi,
im not from Qorix, but saw your Github Issue and maybe i can help here.
This problem is already known and is raised by the json parser, not the KVS. Its already reported to people working on the json lib. The main problem is, that the json wrapper stores "1"/"0" instead of true/false, but the nlohmann backend normally supports true/false.

Changing the order of execution would always lead to one cast not working properly.

But even while the parser has this bug, it will probably be fixed by PR#54, since here we already tell the type which should be used in the json file.
